WOOD=DRESSING MACHINEl Specication of Letters Patent.'

Patented Feb. 5, 1907.

Application filed October 23, 1906. Serial No. 340.149.

T0 all whom it may concern.-

Be it known that I, WILLIAM M. a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Wood-Dressing Machines, of which the following is a specification.

This invention relates more particularly to mechanisms for'dressing wooden moldmgs and analogous articles of curvilinear or irregular outline. The molding-machines, stickers, sandpapering-machines, andother machines by which such moldings and articles are produced usually leave them more or less rough, and they must be dressed or smoothed and cleaned to render them fit for use.

"Ihe purpose of this invention is to rovide an etlicient mechanical device where y such moldings, bars, plates, 'or strips can be successfully dressed to detach and remove raised i'ibers, surface sand,.dust, or other cause of roughness and make them smooth and even, thereby avoiding lthe necessity for cleaning the-se articles vby hand.

The machine or mechanism consists of a rotarycylinder or other rotary support on which are mounted dressing devices, heads, or brushes in such a Way that they are independently secured and can be individually .adjust-ed toward and from the axis of the support to produce for the device as a whole a dressing surface or peri hery which will conform to the outline of t e particular molding or article operated upon.

In the accompanying drawings, Figure 1 is a sideview, partly in section and partly in elevation, of a dressing mechanism embodying the invention. Fi 2 1s a sectional elevation, on an enlarge scale, of one of the dressing devices. Figs.A 3 land!!l are different elevations of a dressing device with di (ferent material. Fig. 5 is an elevation of another form of dressing device. Fig. 6 is an elevation of a. portion of a molding-machine rovided with a dressing-mechanism accor ing to this invention. l

Like letters of reference refer in the several figures.

A represents the'rotary sup' ort for the dressing devices,'heads, or brus es, consisting in the construction shown in the drawings ot a hollow cylinder secured on a central shaft a, which is journaled in suitable bearings B and is provided at one end with a pulley C for a driving-belt. The support may to like parts LUTHER,

be constructed, mounted, and ydriven in any other suitable manner.

D represents dressing devices, heads, or brushes of some material suitable for cleaning or dressing the article to be operated upon, which are arranged around and project radially from the rotary support or cylinder, being mounted thereon so that they can be independently or individually adjusted toward and from the axis of the support or cylinder, whereby the periphe or operative surface of the device as a whdlb will conform to the outline of the article to be operated upon and will en age the various surface portions thereof. simple wa of adjustably mounting these devices, headBsr, or brushes on the support or cylinder is that shown in the drawings, in which the heads or brushes are provided with screw-threaded stems d, screwed into threaded holes d in the. cylinder, in which the stems are clamped after adjustment by jam-nuts d2. These threaded holes are preferably arranged in the cylinder in circular rows side by side, with the holes in I adjoining rows out oi line to enable a close arrangement of the heads or brushes. The number of holesl can be much greater than the number of heads actually employed in order to permit of a variety of arrangements of the heads or brushes to suit moldings or articles of different cont-ours and sizes. Other means could be employed for adjustably mounting the heads or brushes on the suport.

p The heads or brushes may be made of different materials--such, for instance, as Wire, bristles, chamois-skin, or other cleaning or polishing materialgand will vary in construction, depending upon the material employed. The head or brush shown in Fig. 2 is made of wire, the inner ends of the wires being clamped between a socket d and the stem d, on which the socket is screwed.

Figs. 3 and 4 show a head D made of pieces of chamois-skin clamped in a split socket di, while Fig. 5 shows a head D2 with bristles or wires projecting laterally from the socket in order to sweep upright or edge porat the left-hand side of Fig. 1.

rIhe dressing mechanism described may constitute a separate and distinct machine through which the moldings or articles are run after they have been produced in a molding or other machine, or the dressing mech- IOO tins ofthe molding or article, as represented IOS anism may be arranged at the delivery end of a molding or other machine and constitute device With one of the pulleys g of the moldi lengthwise and circumferentially of the suping-machine.l The dressing heads or devices being small and capable of being placed in any necessary arrangement on the support and of being adjusted as necessary to- Ward and from the axis of the support, vthey can be made to engage or sweep all surface portions of articles having agreat-variet of outlines, and they Will thoroughly e ean small angles and corners which cannotV be properly cleaned with the means at present' employed.

l claim as my invention* 1. A dressing mechanism comprising a rotary support, and dressing devices mountedk thereon at different points lengthwise of the support, and individually adjustable toward and from the axis of support, substantially as set forth.

2; A dressing mechanism comprising a rotary'support, and dressing devices 4independ-l ently secured thereon at different points ort and separately adjustable toward and rom the axis ofthe support, substantially as set forth.

I holes, dressing t3. A dressing mechanism comprising a rotary support, and dressing devices mounted thereon, said dressing devices having dressing instrumentalities and separate means at different points for adjusting them toward and from the axis of the su port, substantially as set forth.

4. A ressing mechanism comprising a rotary support, and dressing devices mounted thereon side by side lengthwise of the support., each device comprising a stem adjustlengthwise of said support able on the support toward and from the axis v thereof, and ea head with dressing instrumentalities, substantially as set forth.

. `5. A dressing mechanism comprising a ro.

tary cylinder provided with holes in its periphery, and dressing devices arranged side by side lengthwise of said cylinder and having stems separately adjustable in said holes toward and from the axis of the cylinder, substantially as set forth. v j

6. A dressing mechanism comprising a rotarysupport provided with screw-threaded devices comprising stems screwed in said holes 'and provided With heads at their outer ends and dressing instrumentalities secured in saidheads, and

means for securing said stems in adjusted positions in said threaded holes, substantially' as' set forth.
